LUBRICATING WELT AD SYSTEM-OF USING THE SAME Filed Dec. 51, 1929 ilatented Sept. 29, 1931 i UNITED STATE-.s PATENTepncslgg' ALBERT L. HOWARD, on BRocxToM MASSACHUSETTS, ASSIGNORTOHAMrLToN-wAnE COMPANY, or BaocxToN, MASSACHUSETTS, A CORPORATION,or-MASSACHUSETTS Y LUBRIGATINGWELT SANDS SYSTEM or ISINGTTHE SAME Appiication fued Deember 31, 1929.I serial No. macal This invention relates to improvements in lubricating welting or packing, more pai'- ticularly adapted for use in joints in which direct contact i-s to bek avoided between assembledparts, and a system of'usingthe same. In the constructionof automobile bodies and in otherstructures built up of assembled Vparts where they elements ofu appearance, durability, absorption of vibration and i@ squeaks, and protection from foreign substances in seams is important, it has been customary to employ welting or packing. One example of such usev is in the joint between the fenders and body of automobiles. When in this manner, this packing is called fender welting. It may be usedalso with advantage between the body andchassis, or elsewhere in joints or in seamsibetween metallic surfaces, thereby preventing wearing and ir- 2o ritating noises which would be occasioned by direct rubbing and contact of the parts.

Even with the application of such -welting,`

adjacent surfaces between -metallic partsor between a metallic part and a surface ofthe Welting frequently become dried or abrasive material enters therebetween, destroying the eifectiveness of the welting.

In accordance with the present invention, 1t

4 is proposed to provide a weltingor packing of such construction that a lubricating yinaterial may be employed in connection with it, to prevent undue wearing or kabrasionof the parts. The welting in apreferred form may be constructed by surrounding a porous filler with a suitable Huid-resisting, or preferably fluid-tight covering havingdepending edges extending outwardly from the filler,fforming a fla packiiig portion of the welting. ,Absorbent material, such as felt-roving, wicking or the e which will vcarry asupply of lu ricant, may be forined as aleaf and inserted between the two depending edges-of the` flap portion of the welting and, if desired, may extend into the bead. -This absorbent 'leaf serves to present lubricant evenly over -the Surfaces separated, and holes may be located throughout the flap portion to aid in itsuniform distribution. Y l

The absorbent leaf, filler or the innerk surlike,

faces ofthe covering mayithen'be with lubricant' and the welting adjusted -in place between the parts to be Separated. Any

suitable form of fastening can be-'used to hold ,I

the parts of the welting in place. "Stitching may be `employed Aadjacentfthe bead `iller,

passing thipugh the covering andthe leaf. Additional lubrication may be provided by connecting a lubricant reservoir to lthe bead, l

thereby permitting the lubricant in liquid form to be absorbed by the filler: and distributed'gby means of the filler and-leaf throughout the extent of the welting. Ac-

cordingly, an importantandnovel feature of x i my invention consists in a welting having the capacity of conducting ka fluidlubricant throughout its length, in, combinationy with a vsource for supplying Such lubricant to the Welting. Y f V A weltingl of the construction above set `forth i-s particularly effective for use-,aspacking between the chassisLbody 'and fenders of automobiles because the `absorbent leaf, which mayy be both lubricant-absorbent and ,comypressible, aidsas a paddingy to-permit working of the parts 'with a minimum'of friction, producing a vibration-absorbing effectl of the greatest possible efficiency.,

The filler for the bead not only produces an enlargement which closes the entrancet'othe Joint Plotecingit lfrom dirt, wat-ef or eurer lelgn SllbStIlCcS, butalso `adds to thefgeneral yappearance inproducing -a finished container for the lubricant and toa certain extent acts'asa LSource of supplyfor replen- .`h` lb' tt th tl f.A of the proper width to-serve as the 1S mg u mean o e absorben ea These and otherfeaturesof the. invention vwill be best' understoodiand appreciated from the followingdescription of a preferredemlbodiinent thereof, selected for purposes o of yillustration and Shown in the accompanying construction; and l Fig. 2 is a view in sectionfa-long theline- 2-2 of Fig. 1.

effect.` The filler also acts as a vdistributing one corner more clearly to illuminate/'theV so I 16 'only covered. This lubricant may consist effectively retained;A

sorbent leaf might well -be rolled up to suffi- Ysupply of suitable lubricant.

The Welting includes in its structure a filler or core 10 consisting of'a cord yor other fibrous material which is porous or other- Wise capable of holding and distributing a This is surrounded by a covering 12, having depending edges-Band 14 extending at one side of the iiller. Bet'wveen Ythese edges, an absorbent leaf 16 of sheet material is placed. This Imight take the formrof ailattenedroving or a strip of cellular-product. The parts are then secured in place by stitching 17 passing through the covering and leaf` 16, permitting` Y ingV edges 13an'd 14 of the covering 12.

v,',Ih'ese holes are' shown yas being round but they may be of any suitable shape, slits hav- 'ing been lfound to bee'ffective for the purpose intended.

After" having completed the construction of th'e'wvvelting, the entire flap 24 may be Adipped'into a suitable lubricant or the covering edges-13 Vand 14 turne'dru'p` 'and the leaf of heavy oil, or Where it is applied to the leaf alone, graphite or grease may be used. I The hller 10 also might be saturated With lubriz cant before stitching the parts together. IThe lubricant may be more effectively 'distributed if the lholes 22 on opposite sides 'of the lflap are not'lccated in `'register but y:staggered With respect to each other, as shovvn'in Fig. 2.

VAs an auxiliary lsupply for lubricant, Va reservoir 2'6filled With-.suitable lubricating fluid may be )connected bym'e'an's of a tube "27 toth'e b`ea'd20. If some lubricant-absorb- ',ing'ma-terial 28,su 'ch 'as Waste, is placed Within the reservoir 26,' the 'supply of oil isi-more j .'ll'iecovering material v12f1nay be :of any fluidti'ght composition vvv'hich'is capable kof resistingthefloi'v of both the' lubricant and Walter.

A Welting .saturated with lubricant and constructed in the manner indicated has been k place by clamping bolts or rivets and the continuous application of a lubricant to these fastenings` also assists in increasing their durability. Y i
